COMBINED BLACKBOARD AND DRAWING-CASE.

SPECIFICATION forming part of Letters Patent No. 329,300, dated October 27,1885. Application filed January 12, 1885. Serial No. 152,627. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM A. EMERSON, a citizen of the United States, residing at Leominster,- in the county of Worcester and State of Massachusettshave invented new and useful Improvements in a Combined Drawing-Case and Blackboard, of which the following is a specification.

This invention relates to improvements in art blackboards and drawingcases combined, the object being to provide an improved drawing-case for students, having combined therewith a pivoted blackboard, all arranged .to be employed, as hereinafter set forth, for

facilitating the acquirement of the art of drawing, and particularly so from memory.

In the drawings forming part of this specification, Figure l is a front elevation, and Fig. 6 is a perspective view, of a combined art blackboard and drawing-case constructed according to my invention. Fig. 2 is alongitudinal section on the line a m, Fig. 1. Fig. 3 is a detail view. Figs. 4 and 5 illustrate details of a modified manner of pinning the blackboard to the case. Fig. 7 is a perspective view of the drawing-case, showing the blackboard turned up.

In the drawings, A is the drawing-case, consisting of the flat bottom a, having the side rails, m m, secured one on either edge thereof, the upright end pieces 12 b and end piece I), and the overhanging piece A, secured to the upper edges of the pieces 1), thereby forming a chamber at one end of the case. At the rear side of said chamber, lying transversely across the case and secured to the latter, is a chalk and crayon rest, f. A shaft, 0, whose ends have bearings in the end pieces b, has attached thereto by arms, as shown, a rotating design board, B, the latter being of such length and size as to permit of its being rotated back and forth within said chamber by turning shaft 0, or by giving to the latter a reciprocating rotary motion, and said designboard B is adapted, when rolled forward, to close the front side of said chamber, as in Fig. 6, lying in an inclined position, its outer face having temporarily secured thereon designs 8 8, of any desired description, of which the student is to make a copy or copies. The blackboard t has the rails h h secured to its opposite edges, and is fitted to slide back and forth between the side rails, m, of the case A, its position when pushed quite inward being shown in Figs. 2 and 6. The outer sides of the rails it, next to the rails m, have each a groove, 2, thereinextending from near the rear end to about the center of the rail. A pin, 1%, passes through each rail m, the end of which enters said groove z in the rail h. A pin, 0, is placed in one of the rails h, and a pin, 0, in the rail on the opposite edge of the blackboard, and in a line with said pins on shaft 0 are placed the pins 6 and d, Fig. 3 showing the relative positions of said pins 0 and d when the blackboard is drawn out far enough to bring pin 0 in front of shaft 0, and the position of pin d is there shown directly behind the former pin, 0. In said lastnan1ed figure is also shown the positions of the pins 0 and e with the blackboard in the abovenamed position.

The apparatus is employed and its operation is as follows: Referring now to Fig. 6, the designs 8 8, one or several, are attached to the 'face of board B temporarily, and subject to any desired change, and the student is required to copy said designs upon paper placed on the side of the blackboard t in front of the designs. After the student has made said copies it is desirable that the originals be removed from his sight, and that he be required to redraw said designs from memory, and to bring the blackboard to proper position to draw on, and at the same time carry said designs beyond the view of the student, as shown in Fig. 7, the blackboard i is drawn forward, causing pin 0 (see Fig. 2) to strike pin 6, and, rolling shaft 0, turn the board B over to the position there shown in dotted lines,aud the blackboard, being drawn out until it is brought to a stop by the pins n, is then turned up against the front of the higher part of the case A, as shown in Fig. 7, and bringing its blacked face before the pupil in convenient position to be drawn upon. To restore the parts to the position shown in Fig. 6, the blackboard is swung forward to a fiat position, and being pushed into the case pin 0 moves against pin (1 in shaft 0, rolling the latter and throwing board B forward again.

By reference to Figs. 4 and 5 it will be seen, as there illustrated, that instead of grooving the rails h of the blackboard the railsm of the IOO ' 5 the blackboard and case A to that shown in the other figures of the drawings.

What I claim as my invention is 1. A drawing case, substantially as described, provided with a reciprocally rotating design-board connected to a shaft in said case, and with a blackboard, substantially as described, having a pivotal and sliding connection with the case and adapted to engage with said shaft, combined and operating substantially as set forth. 1

2. A drawing case, substantially as described, having an elevated chamber thereon, a shaft hung in the latter, a design-board attached to said shaft, and a blackboard adapted to slide and swing on said case, and provided with means, substantially as described, for engaging with said shaft when moving under the latter, combined and operating substantially as set forth. 7

3. In combination, the sliding pivoted board *6 and the case A, having an elevated chamber at the rear end thereof, forming a support to hold said board in an upwardly-inclined position, substantially as set forth.

4. In combination, the case A, the shaft 0, provided with the pins d and e, the designboard B, and the blackboard 13, provided with the pins 0 0 and adapted to slide in the case, substantially as shown and described.
